EMC2305 Multiple RPM-Based PWM Fan Controllerfor Five FansPRODUCT FEATURES Datasheet General Description Features The EMC2305 is an SMBus compliant fan controller withup to five independently controlled PWM fan drivers.Each fan driver is controlled by a programmablefrequency PWM driver and Fan Speed Control algorithmthat operates in either a closed loop fashion or as adirectly PWM-controlled device. В„ The closed loop Fan Speed Control algorithm (FSC) hasthe capability to detect aging fans and alert the system.It will likewise detect stalled or locked fans and triggeran interrupt.Additionally, the EMC2305 offers a clock output so thatmultiple devices may be chained and slaved to thesame clock source for optimal performance in largedistributed systems. вЂ”вЂ”вЂ”вЂ”вЂ”вЂ”вЂ”В„В„ В„ …
